Sifu Tim Berkemeier is a master of Traditional Wing Chun Kung Fu, trained under the direct lineage of Grandmaster William Cheung — the man who taught Bruce Lee. With decades of martial arts experience and a reputation built on both wisdom and warriorship, Tim delivers powerful, principle-based instruction rooted in physics, simplicity, and raw functionality. What sets Tim apart is his scientific approach to combat. He teaches by principle — not memorized technique — breaking down movement through the lens of biomechanics, energy, and natural law. To him, combat is physics in motion. Everything is energy. Every action has a purpose. And the simpler it is, the more universally effective it becomes. This isn’t just theory. Tim has worked high-level bodyguard and private security details for major celebrities and high-profile clients — operating in environments where one mistake can be fatal. His training has been pressure-tested in the real world, and his methods are trusted by fighters, business professionals, and parents alike. In addition to hand-to-hand combat, Tim is also a certified firearms instructor with years of competitive shooting experience. His expertise bridges the gap between traditional martial arts and modern tactical training, making him a rare hybrid of old-school discipline and real-world application. Whether it’s fists, blades, or firearms, Tim trains people to respond with clarity, confidence, and precision under pressure. Over the years, he has trained with some of the most respected martial artists in the world across multiple disciplines, yet he remains loyal to one truth: a principle-based system applies to all aspects of combat — whether it’s a street confrontation, self-defense, or internal discipline. Sifu Tim is more than a martial artist — he’s a mentor, strategist, and life architect. Whether he’s teaching combat, mindset, or mission-focused living, his philosophy is consistent: Strip away the fluff, stick to what works, and make it real.
